Parker 17 Super, Which ink Sac

[Paul-H]

Hi guys

Hopefully a quick one.

I need to replace the ink sac on my Parker 17 Super, anyone know if it needs to be anything special or would a normal rubber one work ok, or does it need something special like the Parker 51 types and if it does would a 51 sac fit.

Thanks for any help with this

A standard latex will work (I can't remember the size, but relatively slender), at the cost of losing any sense of how full the pen is. The 51 sac is a wider thing, and won't work.
